The increasing demand for milk and diary products on internal and international markets determines the finding of certain solutions to increase such productions. An important solution is to obtain hybrids between local breeds from various geo- climatic areas and important specialized breeds. This paperwork presents the obtained results from crossbreeding of some effectives of local sheep from breeds like Milk Breed-Palas, Prolific Line-Palas, ţigaie, ţurcană, breed with rams from breeds specialized for milk production, Lacaune and Awassi. There were evaluated and compared under the aspect of total milk production and milked milk, the F1 hybrid sheep from the 5 obtained genotypes (lots of prim pars) with the local breeds (lots of prim pars). Four out of 5 obtained hybrids made at the first lactation a quantity of total and milked milk, significantly bigger than the local breeds. The obtained F1 hybrids, with productions which were superior to the local breeds will be the first links for certain new populations (lines, breeds) specialized for milk.
